Who really needs more power right now? If you need more just get a second GPU. If you already have dual GPU's you are set. Games just aren't pushing graphics like they used to.

I got an answer... try playing games in surround on SLI 570s... some games choke pretty bad if you try to max them. Also, kepler will bring large performance/watt increases due to 32nm fab and ??? so that will be very nice for folding.
